ECO Meter

Notes, Cautions, and Warnings Summary

The following notes, cautions, and warnings apply to ECO meters and are listed below, as well as in the text in each user’s guide.

Notes: Notes provide additional information or tips about operating your meter.
Cautions: Cautions advise against an action that will compromise the ability to collect data or the meter's performance.
WARNINGS: Warnings advise against an action that will damage the instrument.

All ECOs
WARNING! If you are going to build or use a non-WET Labs-built cable, do not use the wire from pin 3 or the ECO meter will be damaged.

Shuttered ECOs
WARNING: Do NOT move the Bio-wiper™ with your finger. This can damage the motor and will void the warranty.

For units with internal batteries:
WARNING! Pin 6 is always “hot.” Be sure to keep the dummy plug on when not in use.

For units with internal pressure sensors
WARNING! Do not exceed 300 m (500 psi).

For units with internal pressure sensors
WARNINGS!
Never touch or push on the transducer.

Never attempt to fill the reservoir except by the procedure below.

ECO Scattering Meters (BB models)
Note
ECO scattering meters are sensitive to AC light. Before making measurement, turn AC lighting off.

WARNING! Always use a regulated power supply to provide power to ECO sensors if not using the 9V battery provided with the test cable: power spikes may damage the meter.

ECOs with internal batteries
Note
Battery units: Always check vent seal plug for full insertion immediately prior to deployment.

WARNING! Do not use acetone or other solvents to clean the sensor.

WARNING! Changing the batteries will require opening the pressure housing of the ECO sensor. Only people qualified to service underwater oceanographic instrumentation should perform this procedure. If this procedure is performed improperly, it could result in catastrophic instrument failure due to flooding or in personal injury or death due to abnormal internal pressure as a result of flooding.

WARNING! The pressure housing is made of plastic material that scratches easily. Do not let the screwdriver slip and scratch the can when removing or replacing the vent plug. Use a toothpick (something softer than the plastic) to remove the O-rings from the vent plug.

Note: A portion of the truss screw head has been removed to allow for venting in case of pressure buildup.
